JOURNAL-LUBRICATIN G DEVICE.

SPECIFICATION forming part of Letters Patent No. 746,243, dated.December 8, 1903.

Application filed February 24:, 1903- Serial No. 144,658. (No model.)

To all whom it may concern:

Be it known that LRALPH BAGGALEY, of Pittsburg, in the county ofAlleghenyvand State of Pennsylvania, have invented a new of which thefollowing is a full, clear, and exact description, reference being badto the ac-' c'ompanying drawings, forming part of this specification, inwhich Figure 1 shows in vertical cross-section a journal-bearingprovided with my lubricating device. Fig. 2 is avertical section on theline II II of Fig. 1. Fig. 3 is a view similar to Fig. 1, showing mydevice modified. Fig. 4

is a side elevation of Fig. 3, partly in vertical central section.

- My invention is designed to provide an ef-- ficient lubricating devicein which .dust and grit are excluded from the oil-cup and from thejournals and in which the oil is supplied continuously and evenly.

I use cotton as the capillary elevator for the lubricant and arrange itso that it will deliver the lubricant by gravity onto a woolen brush orpad placed in the journal so as to deliver a continuous and adequatesupply of clean oil over the entire area of the revolving shaft.

I havefound by experience'that when I place cotton brushes or pads orwaste in contact with a revolving shaft, particularly arapidly-revolving shaft, the friction has the efiect of charring thecotton and converting the fiber practically into a black charcoal. Ihave found that wool is not charred in this manner; but it is not nearlyso good a capillary elevator for the lubricant as cotton fiber. Hence inorder to produce a perfect device I utilize cotton fiber as my elevatorand a wool-en brush or pad or mat or a body of waste of wool as mydistributor for the lubricant over the area of the shaft.

Referring to Figs. 1 and 2 of the drawings,

2 represents the journal which is to be lubri screwed to the walls ofthe chamber 6, and at its upper end it is fitted with a cap or nut 8,

which is screwed'on the bushing and bears upon a gasket 9 at the upperend of lhe tube 5. 10 lO are cotton wicks which extend from the body ofoil in the cup 3 upwardly and thence down through the bushing 7 into thechamber 6, where they rest upon a body of cotton fabric or waste body ofwoolen fiber or waste 12 in contact withthejournal. Thefibrousmaterialllaud 12 is held yieldingly upon the journal by springs13 and an interposed pressure-plate 14. The cup 3 having been chargedwith oil, as shown, the oil is elevated by the capillary action of thewicks to the top of the tubes 5 and thence is carried by the' wicks bythejoint 11, beneath which isa' action .of gravity and capillaryattraction downwardly through the tubes o'arid is discharged uponthefibrous material 11 and 12, by which it is evenly distributed to thejournal. The supply of oilis thus continuous, and

as it is delivered by the wicks it carries no impurities with it. Thecotton wicks,ias above stated, deliver theoil with sufficient freedom,and it is applied by the woolen fiber 12 without chart-ing ordestruction of the latter. The oil-cups 3 may be made of glass, so thatthe quantity of oil therein may be readily observed, and so long as theoilremains. in. the cup the lubricating action continues auto maticallyand without need of attention.

In Figs. 3 and. 4 I show a modified construction of my device, in whichI employ two oilcups 3 3, each having an oil-tube 5 and a bushing 7, bywhich a continuous passage is afiorded for the wicks. In these figuresI. show a body of woolen waste 12, upon which the cotton wicks dischargedirectly and which is held in contact with the journal by a plate 14,acting not by springs, but by gravity.

My device may be modified in various ways by those skilled in the artwithout departing from my invention, since What I claim is- 1.Ajournal-1nbricatingdevicecomprising an oil-cup, a tube therein, abushing extending upwardly within the tube and adapted to contain awick, and a cap on the bushing adapted to hold it; substantially asdescribed.
